The Discussion Settings control how comments are handled on your site.

Youâ€™ll
be able to determine whether comments can post automatically or if they
need to be reviewed and approved before becoming visible to others.
Select your settings here carefully as they will affect how your site is
viewed and perceived by someone else.

You will also be able to
identify words, phrases, IP addresses, email addresses, names and URLs
that you want to â€œblacklistâ€ from being able to make comments on your
site.

In addition, you can decide how â€“ or if â€“ you want the commenterâ€™s picture (avatar) to appear next to their comment.
